Buddleja plant named ‘Podaras #6’

ABSTRACT

A new and distinct cultivar of  Buddleja  plant named ‘Podaras #6’, characterized by its compact, upright and outwardly spreading plant habit; freely flowering habit; sterile light violet-colored flowers; and good garden performance.

Botanical designation: Buddleja davidii×Buddleja alternifolia.

Cultivar denomination: ‘PODARAS #6’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Buddleja plant, botanically known as Buddleja davidii×Buddleja alternifolia and hereinafter referred to by the name ‘Podaras #6’.

The new Buddleja plant is a product of a planned breeding program conducted by the Inventor in Ithaca, N.Y. The objective of the breeding program was to create new compact and sterile Buddleja plants with unique and attractive flower coloration.

The new Buddleja plant originated from a cross-pollination on Mar. 7, 2007 in Ithaca, N.Y., of two unnamed selections of Buddleja davidii×Buddleja alternifolia, not patented. The new Buddleja plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Ithaca, N.Y. in August, 2007.

Asexual reproduction of the new Buddleja plant by cuttings in a controlled greenhouse environment in West Chicago, Ill. since February, 2008, has shown that the unique features of this new Buddleja plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Buddleja have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Podaras #6’. These characteristics in combination distinguish ‘Podaras #6’ as a new and distinct Buddleja plant:

-   -   1. Compact, upright and outwardly spreading plant habit.     -   2. Freely flowering habit.     -   3. Sterile light violet-colored flowers.     -   4. Good garden performance.

Plants of the new Buddleja differ from plants of the parent selections primarily in growth habit as plants of the new Buddleja are more compact and denser than plants of the parent selections.

Plants of the new Buddleja can be compared to plants of Buddleja davidii ‘Pink Delight’, not patented. In side-by-side comparisons, plants of the new Buddleja and ‘Pink Delight’ differed in the following characteristics:

-   -   1. Plants of the new Buddleja were more compact and denser than         plants of ‘Pink Delight’.     -   2. Plants of the new Buddleja and ‘Pink Delight’ differed in         leaf color as plants of ‘Pink Delight’ had silvery-colored         leaves.     -   3. Flowers of plants of the new Buddleja were darker pink in         color than flowers of plants of ‘Pink Delight’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Buddleja plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Buddleja plant.

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘Podaras #6’ grown in a container.

The photograph at the top of the sheet is a close-up view of a typical inflorescence of ‘Podaras #6’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in Arroyo Grande, Calif. under commercial practice during the summer in 12.5-cm containers in a polyethylene-covered greenhouse with day temperatures averaging 21° C. and night temperatures averaging 7° C. Plants were pinched two times and were one year old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
